What are two reasons a user cannot be deactivated?

The correct answer highlights that a user cannot be deactivated if they are the recipient of Workflow Email Alerts. This is due to the functional role that such alerts play in an organization's operations. If a user is receiving these alerts, they typically have ongoing responsibilities or tasks in processes that rely on timely notifications. Deactivating such a user could disrupt workflows, lead to missed notifications, and impact the efficiency of the workflows that depend on their receipt of these alerts.

In most systems, it is crucial to ensure that individuals who play an active part in receiving important notifications remain active users. Therefore, being a recipient of Workflow Email Alerts establishes a need for the user to retain deactivated status to maintain continuity in operations and communication within the organization.
